Corkscrew grass (Juncus effusus "Spiralis"), also known as corkscrew rush, produces medium green stems that curl in a spiral pattern. The upright, vase-shape habit combined with the curly-cue stems adds a sharp texture to landscape plantings.
Hardy in U.S. Department of Agriculture plant hardiness zones 4 through 9,
Corkscrew grass grows best in full to partial sunlight and moist, nutrient-rich soils.
To prevent its spread into undesired garden areas, this plant is best grown in containers buried in the ground.
Water generously. Don't allow the soil to dry out. Foliage will turn yellow then brown if it gets too dry. It's a good idea to keep your corkscrew rush plant in a pot without a drainage hole. Juncus is native to marsh areas, so it loves soggy soil -- even standing water.
Height: 2-3 ft (60-90 cm)
Light: Give it as much full sun as you can. It will tolerate some indirect light.
